I recently started a new job and one of our security cameras went down. I am trying to work out why and want to find out what port the POE cable from the camera plugs into in the switch in the server room.
I am using a cable tester with a Master and Remote unit and its my understanding that when you plug the Remote in one end (By the camera) and the Master in the corresponding other end (In the server room) the lights should blink sequentially in order.
However the issue i am having is that my Master unit seems to blink sequentially with several cables i have tried which means i cannot identify the correct cable.
Why is this the case ? Surely if it is the incorrect cable the lights should not blink at all ?
